Abstract

En myknet polyvinylalkoholslipp-middelblanding for en vandig eller halvvandig fremkallingsbar fleksografisk trykkplate omfatter (a) minst 60% av en sterkt hydro-lysert polyvinylalkohol, basert på den samlede vekt av slippmiddelblanding, og (b) minst 8% mykner, basert på den samlede vekt av slippmiddelblandingen.Oppfinnelsen angår også et vandig eller halvvandig fremkallings-bart fleksografisk lysfølsomt element som omfatter et underlag, et lag av en lysfølsom blanding og et fleksibelt dekkark, hvor den myknede polyvinyl-alkoholslippmiddelblanding er anordnet mellom dekkarket og den lysflsomme blanding. En fremgangsmåte for frem-stilling av trykkrelieffer fra slike elementer er også krevet.A plasticized polyvinyl alcohol release agent composition for an aqueous or semi-aqueous recoverable flexographic printing plate comprises (a) at least 60% of a highly hydrolyzed polyvinyl alcohol, based on the total weight of the release agent composition, and (b) at least 8% plasticizer, based on the total weight. The invention also relates to an aqueous or semi-aqueous recoverable flexographic photosensitive element comprising a substrate, a layer of a photosensitive composition and a flexible cover sheet, wherein the softened polyvinyl alcohol release agent composition is disposed between the cover sheet and the photosensitive composition. A method of making printing reliefs from such elements is also required.
